============================== |
| 5 |
|
| 6 |
checkpoint40pre4 |
| 7 |
o added re-initialisations of utrans,vtrans,rtrans in |
| 8 |
calc_common_factors which are crucial for TAF. |
| 9 |
o extended iMin,jMin range for calc_common_factors, |
| 10 |
calc_diffusivity |
| 11 |
o added option ALLOW_PASSIVE_TRACER |
| 12 |
o a few minor updates and fixes |
| 13 |
|
| 14 |
checkpoint40pre3 |
| 15 |
o created calc_gtr1.F for gad package |
| 16 |
o split the_main_loop and re-introduced forward_step |
| 17 |
o some recomputations of nIter0 for TAMC |
| 18 |
|
| 19 |
checkpoint40pre2 |
| 20 |
o Updated to latest branch of AJA, JMC |
| 21 |
o Added gradient check package |
| 22 |
o Added routines for passive tracer handling |
| 23 |
o Added carbon sequestration sensitivity experiment |
| 24 |
|
| 25 |
checkpoint39 |
| 26 |
o Modifications and fixes to support TAMC |
| 27 |
(mainly missing or wrong directives) |
| 28 |
o Corrected common blocks when fooling TAMC to produce adjoint I/O |
| 29 |
in addummy_in_stepping |
| 30 |
o Updated verification/vero/ (bug fixes in code/, correct pickups in input/) |
| 31 |
o Enabled "sliced" (xz-,yz-) exchanges, needed for obcs. |
| 32 |
o Included following packages: |
| 33 |
cal: calendar |
| 34 |
exf: external forcing |
| 35 |
ecco: essential routines to control use of cal, exf |
| 36 |
(NB: this is not the full ECCO environment) |
| 37 |
o disabled some packages by default in genmake |
| 38 |
|
| 39 |
checkpoint38 |
| 40 |
o see notes_c37_adj.txt |
| 41 |
o corrected wrong layer index in external_forcing_t |
| 42 |
o replaced the_main_loop/forward_step by the_main_loop |
| 43 |
o removed forceoutput from write_state |
| 44 |
(replaced criteria for initial/final state) |
| 45 |
o added runtime flag for pre-C35 pickups: usePickupBeforeC35 |
| 46 |
|
| 47 |
checkpoint37 |
| 48 |
o mdsio.F routine split and packaged in pkg/mdsio |
| 49 |
(mdsio.F and mdsio_gl.F still exist in eesupp/src but are not |
| 50 |
used unless genmake -disable=mdsio) |
| 51 |
o allow a more precise surface-geopotential gradient for the atmosphere |
| 52 |
taking into account the change in space of Alpha (=1/rho) at the surface. |
| 53 |
o variable "etaN" (replace cg2d_x) is the surface R-anomaly [r unit] |
| 54 |
(ocean: sea surface height [m] / atmos: surface pressure anomaly [Pa]) |
| 55 |
o Change units: Phi_Hydrostatic (=phiHyd), Phi_Surface(=cg2d_x) and |
| 56 |
Phi_NonHydrostatic (=cg3d_x), all have now the dimension of a potential |
| 57 |
[m2/s2] (pressure/rhoConst in the ocean ; Geo-Potential in the atmosphere). |
| 58 |
o Time-Average diagnostics defined as a pseudo package "timeave". |
| 59 |
o pickup files : old pickup (before c35) did not work with new code (c35 |
| 60 |
and after) unless activating 2 commented lines in initialise-varia. |
| 61 |
o Non-Hydrostatic pickup file Pb fixed. |
| 62 |
o bug with Rigid-lid version (since c35) fixed. |
| 63 |
|
| 64 |
checkpoint36 |
| 65 |
o implement Crank-Nickelson barotropic time-stepping |
| 66 |
o recover Time-Average diagnostics |
| 67 |
o fix Pb in checkpoint (PR#19) |
| 68 |
o AIM become a standard package ; clean unused CPP_kees |
| 69 |
|
| 70 |
checkpoint35 |
| 71 |
o subtantial rewrite of dynamics.f |
| 72 |
o allows staggered time-stepping |
| 73 |
o packaged obcs, aim (Atmospheric Physics), zonal_filt, shap_filt |
| 74 |
o added bottom drag (linear + quadratic) |
| 75 |
|
| 76 |
checkpoint34 |
| 77 |
o Modified exchange routines for correct reverse simulation. |
| 78 |
o Added verification output to comply with bug fix in impldiff.F |
| 79 |
as of c33 (exp2, natl_box). |
| 80 |
o Corrected store directives in dynamics.F |
| 81 |
o Corrected array boundaries in impldiff.F |
| 82 |
o Corrected array dimensions in gmredi. |
| 83 |
Added temporary scalars to avoid storage by TAMC (gmredi, kpp). |
| 84 |
o Added routine GLOBAL_SUM_INT to global_sum.F |
| 85 |
o Added mdsio_gl.F for ECCO purposes. |
| 86 |
|
| 87 |
checkpoint33 |
| 88 |
o Fixed bug in lower BC in impldiff.F |
| 89 |
o Fixed confusion about units of forcing arrays in FFIELDS.h |
| 90 |
namely Fu,Fv,Qnet,Qsw,EmPmR: |
| 91 |
- Removed verification/natl_box/code/external_fields_scale.F |
| 92 |
(did not differ from that in model/src) |
| 93 |
- Changed units of fu,fv,Qnet,Qsw,EmPmR back to proper units |
| 94 |
(see FFIELDS.h for description) |
| 95 |
- Scale fu,fv,Qnet,Qsw,EmPmR when used in external_forcing_surf.F, |
| 96 |
kpp_calc.F and kpp_transport_t.F |
| 97 |
- Removed model/src/external_fields_scale.F and calls to it |
| 98 |
- verification/natl_box uses flux data with "atmospheric" sign so |
| 99 |
a special version of external_fields_load.F is used to |
| 100 |
change the data as it's read in. This way, the arrays |
| 101 |
have the right units and signs at all times tha a user could |
| 102 |
possibly use them. |
| 103 |
o Corrected genmake to delete a temporary file during configuration |
| 104 |
|
| 105 |
checkpoint32 |
| 106 |
o Scaling of forcing fields moved from external_forcing.F to |
| 107 |
external_fields_scale.F, called directly after loading fields. |
| 108 |
o Surface relaxation terms added to surface tendency fields in |
| 109 |
extra subroutine. |
| 110 |
o impldiff.F changed to avoid storing by TAMC of huge intermediate |
| 111 |
fields. |
| 112 |
o Changes in GMRedi to comply with packaging structure. |
| 113 |
o Modifications and bug fixes in KPP package. |
| 114 |
o Verification experiment for KPP added (verification/nat_box/) |
| 115 |
|
| 116 |
checkpoint31 |
| 117 |
o Packages interface brought in line with defined standard |
| 118 |
-> new routines packages_...F |
| 119 |
-> changes in initialise_fixed.F, initialise_varia.F |
| 120 |
-> enables initialisation interface for ECCO package |
| 121 |
o Rescaling of external forcing fields immediately after read |
| 122 |
(removed from external_forcing.F) |
| 123 |
-> new: surface_fields_scale.F |
| 124 |
-> affects ini_foorcing.F, external_fields_load.F |
| 125 |
o Computation of surface tendencies before tendency updates. |
| 126 |
-> new: external_forcing_surf.F |
| 127 |
o Change of variable names useGMRedi, useKPP, useECCO |
| 128 |
o Further changes in dynamics.F, impldiff.F for TAMC |
| 129 |
o Tested for experiments 0, 2, 4. |
| 130 |
- not yet tested for GMRedi. |
| 131 |

checkpoint29 |
| 143 |
o packaged KPP and GM/Redi |
| 144 |
|
| 145 |
checkpoint28 |
| 146 |
o Corrected initialization of hFacMin for difference vertical coordinates |
| 147 |
o Modified calculation of partial cell thickness to more robust algorithm |
| 148 |
o config_summary.F: replaced write_1D_... by write_0D_... |
| 149 |
read_write.F: added subroutines write_0D_... |
| 150 |
o routines calc_common_factors, calc_gs, calc_gt, calc_phi_hyd, find_rho: |
| 151 |
included some initialisations required for TAMC. |
| 152 |
o routine calc_isoslopes: modified sqrt computation to make it |
| 153 |
differentiable for zero argument. |
| 154 |
o routines dynamics, impldiff: |
| 155 |
included store directives and tape key computations required for TAMC. |
| 156 |
o ALL TAMC related changes are between ifdef ALLOW_AUTODIFF_TAMC |
| 157 |
|
| 158 |
checkpoint27 |
| 159 |
o fixed calc_isoslopes() to so that cancellation of terms in tensor |
| 160 |
formulation works properly with variable resolution. |
| 161 |
o restructured the calling tree between the_model_main() and dynamics() |
| 162 |
o split initialise() into initialise_fixed() and initialise_varia() |
| 163 |

| 164 |
in new routine ini_psurf() |
| 165 |
|
| 166 |
checkpoint26 |
| 167 |
o moved some #ifdef in optional routines to encompass everything |
| 168 |
except the argument declarations. This was using up some memory. |
| 169 |
o fixed macros like _ADT to work with both versions of Linux cpp |
| 170 |
o cleaned up some unused and uninitialized variables |
| 171 |
(helps when debugging with strict compile options) |

(this is was partly for OBCs and NH but also in anticipation of |
| 184 |
an explicit free-surface option) |
| 185 |
o initial state input files for U and V |
| 186 |
|
| 187 |
checkpoint24 |
| 188 |

| 195 |
|
| 196 |
checkpoint22 |
| 197 |

| 230 |
|
| 231 |
checkpoint16 |
| 232 |
o Minor changes to exchange routines to support |
| 233 |
accumulation in reverse mode. Adjoint of an |
| 234 |
assignment is an addition. |
| 235 |
o Changes to support compilation by TAMC (LR(1) |
| 236 |

| 244 |
o Hooks for sharing data via DMA, Arctic, Memory Channel, |
| 245 |
shmput/shmget, VIA, SYSV shmem and every other cool |
| 246 |
communication method. |
| 247 |
|
| 248 |
checkpoint14 |

| 251 |
|
| 252 |
checkpoint13 |
| 253 |
Release which corrects global_max problem and a couple |
| 254 |
of KGM time-averaging diagnostic errors. Also contains |
| 255 |
a double-gyre experiment setup as well as the baseline |
| 256 |
4 degree global template. The double gyre template is |
| 257 |
organised to allow it to be applied automatically to |
| 258 |
the baseline configuration. |
| 259 |
|
| 260 |
branch-point-rdot |
| 261 |
A few tidy-ups have been made bt the real point of this |
| 262 |
check-point (excuse the pun) is to allow a branch to be |
| 263 |
made for the purposes of adding the rDot alterations. |
| 264 |
I don't want to commit the rDot to the main-trunk until |
| 265 |
we've actually tested it... |
| 266 |
|
| 267 |
